The Rubbermaid Commercial Web Foot Shrinkless Mop has a pre-laundered, colorfast four-ply yarn made with a blend of post-work cotton and synthetic fibers that will not shrink or fade with repeated launderings and with protective fibers woven into the yarn toavoid foul smell and stains. This wet mop has looped ends and a woven tailband to reduce tangling and fraying for better performance and longer product life. It has a five-inch headband for use with clamp style mop handles (sold separately). The headband is a PVC-coated mesh that avoids moisture retention. Color-coded as part of a zone isolation system to help minimize cross-mix. This wet mop head is suitable for use in commercial and work applications.
